Im running "Acronis Backup & Recovery 10 Server for Windows" on Windows Server 2008.
I get a file i/o error when starting an incremental backup job. I'm trying to backup files located on another computer (Windows XP machine). The files are locates on a shared disks, and the disk is mapped as a network drive on the server machine.
The disk is mapped as the "Y" drive, I managed to create a backup job succesfully and it shows me the number of files and folders on the network drive before I save the backup job.
But when I run the job, it gives me an error (see below) with detail \\?\Y:\Download. Where is "\\?\" coming from ? I suppose it should be the machine name on which the shared disk is located, but I mapped the disk as a local drive ?
I also tried specifying the path "\\Machine Name\Shared Drive\..." but the backup job won't accept this as a valid path ?

Someone has an idea what the problem is ?

I think ABR10 prefers UNC names rather than mapped drives, but I could be thinking about a totally different piece of software I used to support.

Hello LST and bodgy!

Thank you for reporting about the issue and for valuable comments!

As bodgy already mentioned, you need to specify the full UNC path to the drive, using the ip address of the machine, so it should look like

\\[ip address]\[shared folder name]
